As I can see - loop by ceph config generate-minimal-conf ->  ceph config assimilate-conf -i /etc/ceph/ceph.conf

Thanks for the help.

If you do have a node with 20-30% cpu, it will help to show its listing.

when you say loop, you mean you are see-ing different process-ids  each time ? is this after re-booting ?

Hmm. I thought you were helping me. 🙂

Yes, I seeing different process-ids each time (it is visible in the previous post).

No, after reboot the node is working fine.

Now I have two nodes working normally (after rebooting) and four with 20-30% load and constantly restarting

/bin/sh -c ceph config generate-minimal-conf > /etc/ceph/ceph.conf.new

/bin/sh -c ceph config assimilate-conf -i /etc/ceph/ceph.conf

Thanks for your help. you can reboot the nodes, we will test and try to reproduce this.
